Fine needle sampling without aspiration.

Four hundred and ten thyroid nodules, 127 breast lumps and 43 lymph nodes were sampled and analyzed to compare the classical aspiration (ASP) technique with the non aspiration needle jab (NASP) technique. The adequacy of cellularity, significant blood staining and the discomfort felt by the patient were assessed and statistically analyzed. The non aspiration technique was found to be superior to the classical aspiration technique for fine needle sampling of thyroid in all aspects. However, for breast lesions, while the discomfort felt and the staining with blood was less with the non aspiration technique, the overall cellular yield was unsatisfactory. The adequacy of cellular yield was, however, comparable for malignant breast lesions with either technique. For lymph node sampling, both techniques showed equivalent results with regard to the cellularity but, the NASP technique was superior in other aspects. Although the overall patient discomfort and blood staining was significantly less, the adequacy of the cellularity was influenced by the site and the nature of the lesion. Thus it can be concluded that the technique needs to be selected depending on the anatomic site, the clinical situation, the personal experience and the preference of the operator.
